# Correspondence. The Design of Jetties

*In his paper " The Design of Jetties," Mr. Minikin has given us yet another piling formula. He does so because he is of the opinion (and rightly so) that a piling formula should contain a factor which makes allowance for the embedded length of the pile. This, it is stated in the paper, the Hiley formula does not do. That statement is clearly based on the assumption that the "c" in the Hiley formula is the temporary compression from tables.
